Why it exists
Useful information is often scattered.
A calculator may live in one place, nutrition advice somewhere else, and the explanation behind both in a third. The result is often a precise-looking number with little context, or lots of context with no practical next step.
FitCalc aims to connect useful estimates, practical tools, and understandable explanations while remaining clear about uncertainty.
How information is handled
Transparent methods, practical recommendations.
Show the method
Equations, assumptions, limitations, and review context are documented where appropriate.
Separate result from judgment
Mechanical calculations, evidence-informed ranges, and FitCalc recommendations are not treated as the same thing.
Avoid false precision
Results are starting points to compare with consistent real-world trends, not guarantees.
Correct and update
Sources and explanations are reviewed, and readers can report a concern or correction.
Privacy by default
No account is currently required.
FitCalc calculations run in your browser. When you approve persistence, supported profile and product state stays local to that browser and device. It does not create an account or sync elsewhere.
Analytics consent and newsletter subscriptions are separate systems. You can clear saved FitCalc product data independently. The Privacy page explains the current behavior in detail.
A clear boundary
FitCalc is educational, not medical care.
FitCalc does not diagnose conditions, provide individualized clinical nutrition, or replace advice from a qualified healthcare professional. Use the tools as planning references and seek appropriate professional guidance when your health or circumstances require it.
